Have you tried adding an .exe extension to csi?

Like: "c:\home\chicken-trunk\bin\csi.exe"

I know it sounds stupid...

That's not going to be a problem: filenames (or directory names)  
shorter than 8 chars but containing a space are still considered long  
names and are given a DOS-compatible short name.  So even a short "a  
b" becomes ab~1.

You could try and translate the first filename (the csi executable) to  
a short name and use single quotes on the rest of the line, assuming  
the C library csi is linked to understands single quotes:

c:\home\chicke~1\bin\csi -bnq -e '(require-library setup-api)' -e  
'(import setup-api)' 'c:\...some...path...\defstruct.setup'


Anyways, I think you should dump system(3) and just use CreateProcess:

char *exe = "c:\\home\\chicken-trunk\\bin\\csi.exe";
char *cmdline = "csi -bnq -e \"(require-library setup-api)\" -e  
\"(import setup-api)\" \"c:\\...some...path...\\defstruct.setup\"";

STARTUPINFO si;
PROCESS_INFORMATION pi;
memset(&si, 0, sizeof(si));
si.cb = sizeof(si);

if (! CreateProcess(exe, cmdline, 0,0,0,0,0,0, &si, &pi)) {
        printf("Error %d executing:\n%s\n%s\n", GetLastError(), exe, cmdline);
        exit(1);
}
